I'm trying to make animations on key presses. My code seems to partially work but if you click the key twice or click 2 keys at the same time it breaks and the animation gets stuck on one frame. I was wondering if anyone had a better way of doing this.
My Code:
import greenfoot.*;
public class Cole extends Actor
{
private final GreenfootImage RMstart= new GreenfootImage("ColeIdle1.png");
private final GreenfootImage RMwalk1= new GreenfootImage("ColeMoore1.png");
private final GreenfootImage RMwalk2= new GreenfootImage("ColeMoore2.png");
private final GreenfootImage RMwalk3= new GreenfootImage("ColeMoore3.png");
private final GreenfootImage RMwalk4= new GreenfootImage("ColeMoore4.png");
private final GreenfootImage RMp1 = new GreenfootImage("ColeMoorep1.png");
private final GreenfootImage RMp2 = new GreenfootImage("ColeMoorep2.png");
private final GreenfootImage RMp3 = new GreenfootImage("ColeMoorep3.png");
private final GreenfootImage RMp4 = new GreenfootImage("ColeMoorep4.png");
private final GreenfootImage RMp5 = new GreenfootImage("ColeMoorep5.png");
private final GreenfootImage RMp6 = new GreenfootImage("ColeMoorep6.png");
private final GreenfootImage LMstart= new GreenfootImage(RMstart);
private final GreenfootImage LMwalk1 = new GreenfootImage(RMwalk1);
private final GreenfootImage LMwalk2 = new GreenfootImage(RMwalk2);
private final GreenfootImage LMwalk3 = new GreenfootImage(RMwalk3);
private final GreenfootImage LMwalk4 = new GreenfootImage(RMwalk4);
private final GreenfootImage LMp1 = new GreenfootImage(RMp1);
private final GreenfootImage LMp2 = new GreenfootImage(RMp2);
private final GreenfootImage LMp3 = new GreenfootImage(RMp3);
private final GreenfootImage LMp4 = new GreenfootImage(RMp4);
private final GreenfootImage LMp5 = new GreenfootImage(RMp5);
private final GreenfootImage LMp6 = new GreenfootImage(RMp6);
private int speed = 3;
private int frame;
private boolean walking;
